altos/lpc: Handle USB reset by resetting internal state2016-06-10T21:33:50+00:00Keith Packardkeithp@keithp.com2016-06-10T21:33:50+00:00urn:sha1:54f8d53584d0a902676b441cd122c01cd54f2283
Just like stmf0, this clears internal state at USB reset time so the
driver can survive host OS reboots.

altos/lpc: Double buffer USB data transfers2015-02-06T00:15:04+00:00Keith Packardkeithp@keithp.com2015-01-16T09:09:26+00:00urn:sha1:9fac8b639d2142c90eb95771cda1f6559e987db2
This allocates twice the space in the USB memory so that transactions
can be double buffered without using separate CPU memory.

altos/lpc: Clean up USB endpoint access functions2015-02-06T00:14:23+00:00Keith Packardkeithp@keithp.com2015-02-06T00:08:44+00:00urn:sha1:0671b3c8c24c9f33be77a10315c4669f33c516d7
The USB device endpoints can have two pointers in them, but we use
only the first. Fix the access functions to take an index as to which
we want so that we can disable the other address registers with them
instead of requiring open-coded access.

There's something screwy going on, sticking garbage in the input
buffer at boot time

These got merged when we were down in Auckland, but before they'd been
finished. Transmitting worked fine, but receiving was mis-configuring
the OUT buffer size in the hardware.

The LPC stuff isn't actually very useful and TeleGPS uses a custom pin
instead, and was using HAS_USB_CONNECT to mean the same thing. That
wasn't good.

This lets other bits of the code know when USB has been connected.
